Briley Ultimate Ultralight tubset

Briley Ultimate Ultralight tubset 20,28 & 410, these were in my stock K80 30" barrels and fit with an extended Briley choke. The tubes are 30 3/4" and they are flush to the end of the barrel choke giving you an almost 31" barrel when the tube set is installed. They are in great shape and each barrel comes with one extra choke and the 2 Briley chokes to hold the tube set. The ultimate part of the tube set means they are straight rifled. also come with hammer, knock out. PM me with questions, this is for the Subgauge tubes and chokes only , no barrel

1200 shipped brand new they are $1900 feel free to make me an offer if you would like

Thank you

 

Please update the OD for the tubes
Last picture with the caliper does not mean anything
Bore size must be in inch or mm
For an example - 18.5mm or 0.73inch
Good luck with the sake

 

Thank you, pls correct me if i am wrong. The caliper reads .723 for the OD of the 20ga tube. this would be held on the exit end of the barrel by the Briley choke tube at .005 constriction taking the bore from .730 to .728 keeping the subgauge tube snug, correct?
